BALTIMORE -- Seeking additional opinions on his injured right knee, Yankees left-hander CC Sabathia canceled his appointment with Dr. James Andrews and set up visits with two other orthopedic specialists, the team announced on Friday.

Sabathia had been scheduled to see Andrews on Monday. Instead, he has lined up an appointment with Dodgers team physician Dr. Neal ElAttrache, and has already been seen by Rangers team physician Dr. Keith Meister.

The Yankees have not released any details on the visits, but they remain unsure if Sabathia will be able to return this season; manager Joe Girardi has said that it is "fair to say" that Sabathia's year is over. It has been suggested that Sabathia may need microfracture surgery in his right knee, which has been said to have significant cartilage damage.

Sabathia was 3-4 with a 5.28 ERA in eight starts this season, and was placed on the disabled list following a May 10 outing in Milwaukee. He had been aiming to return to the rotation shortly after the All-Star break, but again experienced swelling and inflammation after a Minor League rehab start earlier this month.
